This router does not support static domain name resolution services because the intranet has changed routers. So you can only set up a DNS service yourself.
The DNS server software chooses bind, and directly yum installs bind on-line. The other two package bind-libs,bind-utils are updated directly:
Yum-y Install bind
The installation process is not released.
After loading, configuration file:/etc/named.conf (no bind-chroot, can increase security, but the intranet is not installed)
To edit the named.conf configuration file:
named.conf//// provided by red hat bind package to configure the isc bind named (8) DNS// server as a caching only nameserver (as a localhost dns resolver only).//// see /usr/share/doc/ bind*/sample/ for example named configuration files.//options {listen-on PORT 53 { ANY; };LISTEN-ON-V6 PORT 53 { ::1;&NBSP,};d irectory "/ Var/named ";d ump-file "/var/named/data/cache_dump.db "; statistics-file "/var/named/data/named_stats.txt"; memstatistics-file "/var/named/data/named_mem_stats.txt";allow-query { any; }; //here is the query permission for the domain name. The default is localhost, which is to allow only native queries. Recursion yes;dnssec-enable yes;dnssec-validation yes;dnssec-lookaside auto;/* path to isc dlv key */bindkeys-file " /etc/named.iscdlv.key ";managed-keys-directory "/var/named/dynamic ";}; logging { channel default_debug { file "Data/named.run" ; severity dynamic; };}; zone "." IN {type hint;file "named.ca";};/ / include "/etc/named/named.rfc1912.zones";include "/etc/named/named.mydomain.cn.zone"; //because this file is to be used, so specify to this file include "/etc/named.root.key";
Then look at Named.mydomain.cn.zone This file, this file is mainly to add domain information:
[Email protected] named]# more Named.mydomain.cn.zone//named.rfc1912.zones:////provided by Red Hat Caching-nameserver Package////ISC BIND named zone configuration for zones recommended by//RFC 1912 Section 4.1:localhost TLDs and Addre SS zones//and http://www.ietf.org/internet-drafts/draft-ietf-dnsop-default-local-zones-02.txt//(c)-R W franks// see/usr/share/doc/bind*/sample/for Example named Configuration Files.//zone "mydomain.cn" in {type Master;file "/etc/ Named/mydomain.cn.zone "; The content of this file is to parse the contents of the article Allow-update {none;};};
Contents of the Mydomain.cn.zone file:
[[email protected] named]# more mydomain.cn.zone $TTL 1D@ IN SOA @ rname.invalid. ( 0 ; serial 1D ; refresh 1h ; retry 1W ; expire 3H ) ; minimum NS @ A 192.168.18.200 aaaa ::1wikiina192.168.18.200 // These three are the entries I added myself to parse Pmsina192.168.18.200designinA192.168.18.200
Online said the three before the addition of a MX, where no addition can also be successfully resolved. Added the instead of the time to start the error, so directly did not want the article.
Now modify the nameserver=192.168.18.200 on the other host (because the IP of my DNS service host is also this), and then use the Dig command to view the following:
root># dig wiki.mydomain.cn; <<>> dig 9.8.2rc1-redhat-9.8.2-0.17.rc1.el6_4.6 <<>> wiki.mydomain.cn;; global options: +cmd;; Got answer:;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 19423;; flags: qr aa rd ra; query: 1, answer: 1, authority: 1, ADDITIONAL: 2;; QUESTION SECTION:;wiki.mydomain.cn.INA;; answer section:wiki.mydomain.cn.86400ina192.168.18.200 //return the IP address correctly here;; AUTHORITY SECTION:mydomain.cn.86400INNSmydomain.cn.;; ADDITIONAL SECTION:mydomain.cn.86400INA192.168.18.200mydomain.cn.86400INAAAA::1;; Query time: 0 msec;; server: 192.168.18.200#53 (192.168.18.200); WHEN: Thu Aug 20 17:01:55 2015;; msg size rcvd: 105
The resolution is successful here.
